> Impala needs a way to do introspection on the partition schema to give the use a reasonable "SHOW CREATE TABLE". For Hash bucketed tables this can be achieved, but for range partitioned tables it is not possible.
> One solution would be to iterate over all the tablets and fetch the stop partition keys and extract the range component, however, this would require the PartitionSchema to have a method to decode a PartialRow from byte[].
